Abstract: PROBLEM TO BE SOLVED: To obtain a cholesteric layer material with improved color impression and to provide a method for manufacturing the same. SOLUTION: In this material, the crosslinked cholesteric layer exhibits an interference fringe pattern which is homogeneous across the whole range of thickness. The cholesteric layer material of this invention and products derived from the same are superb in that their color does not go out of registration in a visually detectable way.

Abstract: Rod-shaped apatite crystals are such that the length:breadth ratio is \-5; and the hydroxide and fluoride ions can be exchanged. Rod-shaped apatite crystals of formula Ca5(PO4)3(OH)x(F)y are such that: (i) the length:breadth ratio is \-5; and (ii) x + y = 1 such that when x or y is not zero the crystals exist as single hydroxide and fluoride apatite crystals and/or a mixture of mixed crystals and (1-x). 100% of the hydroxide ions can be replaced by fluoride ions when y = zero.

Abstract: The invention relates to rod-shaped apatite crystals of formula Ca5(PO4)3(OH)xFy, comprising the following characteristics: a) the length-to - width-ratio of the crystal is at least >= 5 and b) x + y represent 1, in the case where x or y 0, the total amount of the crystals exist as single hydroxylapatite crystals and fluorapatite crystals and/or as a mixture of mixed crystals, whereby in relation to the total amount of the crystals, (1 - x). 100 % of the hydroxidions are replaced by fluoridions in the case where y = 0. The invention also relates to dispersions which contain said rod-shaped apatite crystals, in addition to a method for producing said dispersions or apatite crystals.

Abstract: Cholesteric laminate material has at least one 3-dimensionally crosslinked, oriented cholesteric layer (I) showing a homogeneous interference line pattern over the entire thickness. Independent claims are also included for the following: (a) cholesteric pigment comprising layer(s) (I) with an average particle size of 5-50 mu m and thickness of 0.2-5 mu m; (b) compositions containing the pigment(s); (c) polarizers, comprising the laminate and optionally a substrate foil; (d) broad band polarizers comprising laminates with a total thickness of about 2-50 mu m (without substrate film) and 3-20 cholesteric layers with attuned reflection maxima; and (e) the production of the laminate with layer(s) (I).
